CHAPTER 18 DMA CONTROLLER
18.5.5 UART consecutive reception + ACK transmission
A flowchart illustrating an example of setting for UART consecutive reception + ACK transmission is shown below.
• Consecutively receives data from UART0 and outputs ACK to P10 on completion of reception.
• DMA channel 0 is used for DMA transfer.
• DMA start source: Software trigger (DMA transfer on occurrence of an interrupt is disabled.)
• Transfers FFF12H of UART receive data register 0 (RXD0) to 64 bytes of FFE00H to FFE3FH of RAM.
